Time: chrony replaces timesyncd, with NICT/JP-pool NTP primary and gpsd SHM as an offline-only refclock; makestep any time and fake-hwclock cover the battery-less RTC. Antenna: the modem cleared the supply again after the service set it, so the service is now idempotent, configurable (ANTENNA=active|passive, passive keeps it off) and re-checked by a 30 s timer. gpsd: a gpsdctl udev hook spawned a stray gpsd without -n at boot that blocked the real service; gpsd.service now binds to the NMEA device. GNSS: CGNSSMODE=15 (GLONASS, BeiDou, Galileo, QZSS) and all supported NMEA sentences; both persist across a modem reset. Adds sim7600-at. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

Jetson Orin Nano environment setup for doing things in a car
Part of Project Yukart, making an old 2008 Mitsubishi Z27AG a bit smarter with modern technologies.
This file serves as the minimalist portal to other docs
What this repo is about
Jetson Orin Nano is an ARM SBC running a custom kernel Ubuntu (Nvidia Jetpack), so many things are not readily available.
- For what is considered necessary (and why), refer to the bill of materials;
- For implementation practice guidelines, refer to the guidelines;
